Irrigation System

Shut off the anti-siphon valve that serves irrigation system. Check the red flow-indicator triangle at the water meter. If the flow indicator stopped moving, the irrigation system is the problem.

Main Service Line

First, you need to find your water shutoff valve. This is usually in your front yard near the sewer riser cap, in your garage, or near your water softener unit. Shut off the valve, cutting off all water to your home, and go in the house and turn on a faucet to make sure the water is off. Check the red flow-indicator triangle at the meter. If the red triangle is moving, the leak is between the shutoff valve and the water meter.

Pools

This four-step bucket test may help you determine if you have a leak or a high evaporation rate.

1. Turn off the automatic fill valve
2. Place a bucket on a step where the bucket rim is at least a few inches above the water line. Place a heavy weight in the bucket and add water until the water level inside the bucket is equal with the water level in the pool
3. Leave the bucket and pool undistributed for several hot days, and then compare the water level in the bucket to the water level in the pool
4. If the water level in the bucket is noticeably higher than the water level in the pool, you may be losing water to a leak. Contact a pool leak detection specialist
